TITLE:
摘要: 目的:建立狗皮膏的气相色谱指纹图谱。方法:采用气相色谱法。色谱柱为弹性石英毛细管柱,程序升温,进样口温度为220 ℃,检测器为氢火焰离子化检测器,温度为250 ℃,分流进样量为1 μl,分流比为20 ∶ 1。以丁香酚色谱峰为参照峰,分析5家生产企业32批狗皮膏,采用中药指纹图谱相似度计算软件(2009版)进行共有峰鉴定和相似度评价,并对32批样品的特征图谱进行聚类分析。结果:32批狗皮膏共有11个峰,5家生产企业32批样品间特征图谱相似度低,可聚为5类。结论:所建立的特征图谱专属性强,结果稳定,可为狗皮膏的质量评估和控制提供依据。
ABSTRACT: OBJECTIVE:To establish the GC specific chromatogram of Goupi cream. METHODS: Gas chromatography was performed on the column of fused silica capillary column by programmed temperature, injection temperature was 220 ℃, detector was hydrogen flame ionization detector with temperature of 250 ℃, the injection volume was 1 μl and split ratio of 20 ∶ 1. The eugenol chromatographic peak was used as reference peak to determine the 32 batches of Goupi cream from 5 enterprises, TCM fingerprint similarity calculation software (2009 edition) was conducted for the common peaks identification and similarity evaluation, and the specific chromatogram cluster analysis of 32 batches of samples. RESULTS: There were totally 11 common peaks in the 32 batches of Goupi cream, the 32 batches of samples from different enterprises showed low similarity and could be clustered into 5 types. CONCLUSIONS: The established specific chromatogram is specific and stable, and can provide reference for the quality evaluation and control of Goupi cream.
